(12-26) 13:07 PST BAY POINT -- A Bay Point teenager was arrested Saturday on suspicion of killing a Martinez teen almost four months ago, authorities said.

Daniel Castano, 18, was arrested at a home on the 2700 block of Carpinteria Drive in Antioch around 4 p.m. after Contra Costa County Sheriff's deputies tracked him to the home, said sheriff's spokesman Jimmy Lee.

Officer surrounded the house, and Castano tried to run away but was caught in a neighbor's yard, Lee said.

Castano is suspected of killing Fernando Gonzalez, a 17-year-old Martinez resident, on Sept. 6 in Bay Point, authorities said. Gonzalez was found sitting in a vehicle after police responded to calls of a shooting near Marina Drive and Inlet Drive. Sheriff's deputies began CPR but he was pronounced dead soon after. He died of gunshot wounds to the chest.

Castano was booked into the Martinez jail on suspicion of murder and participation in a criminal street gang, Lee said. He is being held in lieu of $2,050,000 bail.
